Overtime calculator: weekly hours and gross pay

Enter start, end and break for each day and see how far you are over or under your weekly target. Or turn overtime hours into a gross amount from your hourly or monthly pay.

Week calculator

The example is filled in already. Change the times; empty days count as days off.

Contract hours per week, for example 40 or 37:30.

A positive value is a time difference, not a claim to pay. The calculator does not check daily limits, working-time models or absences that count as worked.

Overtime pay: work out the gross amount

Turns overtime hours into a gross amount with your hourly or monthly pay and the premium you agreed. It takes a positive difference from the week calculator; you can also enter the hours directly.

In the same currency as your pay. Gross amount before tax and social security, not net. Whether overtime is paid, and with what premium, depends on the law, collective agreements and your contract; see below.

How to work out overtime

  1. Hours per day. End minus start minus break. 07:45 to 17:15 with a 60-minute break is 8 hours 30 minutes.
  2. The week's total. Add all days, in hours and minutes or in decimal hours.
  3. Compare with the target. Total minus weekly target. 41:15 against a 40-hour target is a difference of 1 hour 15 minutes; a negative result means hours short. Whether that becomes paid overtime depends on your contract and the law.
  4. Note who wanted it. For later pay, what counts is not only the time but also that your employer ordered, approved or tolerated the extra work. Write that down as you go.

What applies in Germany, Austria and Switzerland?

A short overview for employees, not legal advice. Collective agreements and contracts often go further than the law, and some sectors have special rules.

Germany

Working time may not exceed 8 hours per working day; up to 10 hours are allowed if 8 hours per working day are not exceeded on average over six months or 24 weeks.[1]

There is no general statutory overtime premium; whether overtime is paid or offset with time off depends mainly on collective agreements and the contract. Pay can be owed even without an express agreement, where the work could only be expected against pay. Claiming pay means showing that you worked the hours and that the employer ordered, approved or tolerated them, or that they were needed to get the work done.[2][3]

Pay claims are, as a rule, time-barred after three years, counted from the end of the year in which they arose and you knew of them or should have known. Many contracts and collective agreements, however, set cut-off periods of a few months after which unclaimed hours lapse. Overtime premiums are subject to income tax; only premiums for Sunday, holiday and night work are tax-free, within limits.[4][5][6]

Breaks are not working time: over 6 hours you are owed at least 30 minutes, over 9 hours at least 45, splittable into parts of at least 15 minutes.[7]

Austria

Normal working time is generally 8 hours a day and 40 hours a week. Overtime earns a premium of 50 percent or equivalent time off, meaning an hour and a half off for each hour of overtime. Over 6 hours of work you are owed a break of at least 30 minutes.[8]

With increased workload, generally at most 20 hours of overtime a week are allowed; a working day may not exceed 12 hours and a week 60, and over 17 weeks at most 48 hours on average. If you work part-time beyond your agreed hours but below normal working time, that is additional work with, as a rule, a 25 percent premium, with exceptions. Collective agreements can differ.[9][8]

Switzerland

Overtime, meaning hours beyond your contract hours up to the statutory maximum, is paid with a premium of 25 percent or, if you agree, offset with time off of at least equal length; a written contract can exclude the premium or the pay altogether.[10]

Separate from that is excess time beyond the statutory maximum of 45 or 50 hours a week. It is generally limited to two hours a day and 170 or 140 hours a year. It carries a premium of at least 25 percent unless offset with time off by agreement; for office staff, technical and other staff and sales staff in large retail businesses only for the part above 60 hours a year.[11][12]

Frequent questions

How do I calculate my overtime?

For each day, end minus start minus break; add the days and subtract your contract hours for the week. A positive result is time above the target, a negative one hours short. Whether and how the extra time is paid depends on your contract and the law.

How do I get my hourly rate from my monthly pay?

Monthly pay times 12, divided by 52 weeks and by your weekly hours. 4000 a month at 40 hours a week is 4000 × 12 ÷ 52 ÷ 40 = 23.08 an hour. With a 13th month's pay, use 13 instead of 12.

Do breaks count as working time?

No. Rest breaks are not working time and are deducted. In Switzerland they count as working time if you may not leave the workplace during the break.[7][13]

How much overtime is allowed in Germany?

The Working Time Act limits work to 8 hours per working day, up to 10 hours if the average over six months or 24 weeks stays at 8 hours. With six working days that is 48 hours a week on average.[1]

Do I get a premium for overtime?

Germany has no general statutory premium; it comes from collective agreements or the contract. Austrian law provides 50 percent for overtime and, as a rule, 25 percent for part-time additional work. Swiss law provides 25 percent, though a written contract can provide otherwise for Swiss overtime.[8][10]

Does the calculator work out net pay?

No, gross only. What is left after income tax and social security depends on your tax class or rate, your canton or country and the rest of your pay. In Germany the official wage tax calculator of the Federal Ministry of Finance works out the wage tax, without social security; Austria's Ministry of Finance offers a gross-to-net calculator.[14][15]

What about hours short?

If you work less than the target, the balance goes negative. Whether you must make it up depends on who caused it and on what your contract says about working-time accounts.
